Hi,

Perhaps:

par(mfrow=c(2,2))
hist(as.numeric(as.character(B[,1])),col="lightblue", border="pink")
hist(as.numeric(as.character(A[,1])),col="yellow", border="pink")

or

hist(as.numeric(as.character(B[,1])),col="lightblue", border="pink")
par(new=T)
hist(as.numeric(as.character(A[,1])),col="yellow", border="pink")
